Spring2.6.3:配置DataSource：'url‘属性失败

Question

我创建了一个新的Spring项目，并在application.properties中指定了db设置：

spring.jpa.hibernate.ddl-auto=update
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
spring.datasource.url=jdbc:mysql://localhost:3306/mydb?&useLegacyDatetimeCode=false&serverTimezone=UTC&useUnicode=yes&character_set_server=utf8mb4
spring.datasource.username=.....
spring.datasource.password=.....

在pom.xml中，我有mysql依赖项：

<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
</dependency>

我也做过maven -> Update..。

启动项目时，控制台说：

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

我不明白.我只是提供了他needs...the datasource.url.

当我更改spring version to 2.3.0.RELEASE时，...it会工作。但是为什么不和newer one 2.6.3一起

Answer 1

据我所知，Spring .properties文件的键值使用kebab。

你有

spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver

当它应该是

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
